UNITED STATES PATENT OFFICE.

ELAM M QUERY, oE'HARRIs DEPOT, 'NORTH CAROLINA.

IMPROVEM ENT IN SUIBSOIL-PLOWS.

To all whom it may concern:

Be it known that I, ELAM M. QUERY, ot' Harris Depot, in the county ofCabarrus, and in the State otNorth Carolina, have invented cer- 1 tainnew and useful Improvements in Subsoil- Plowsyand I do hereby declarethat the-following is a t'ull,clear,aud exact description thereot',reference being had to the accompanying drawing, and to the letters ofreference marked thereon, making a part ofthis specitication.

The nature of my invention consists in the construction and arrangementot' a subsoil- ,a plow, as will be hereinafter, fully described.

In order to enableothers skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe Yitsconstruction and operation, referring to the annexed drawing, whichrepresen ts a perspective view of my invention.

A represents the usual plow-stock, with the plow B attached at its lowerend. C is the plow-beam, and `D the handles.

On the rear side of the plow-stock A is aftixed a ratchet-bar, a, nearthe upper end, and a wooden subsoil-,plow beam,E, is` attached hy meansot' a bolt, b, which is passed through a slot in the plow-stock A andthe ratchet-plate c. The bolt b then passes through a hole in the beamE, and is secured by a thumh-nut,d. The upper front corner ofthe beam Eis metalshod, and bears against one ofthe teeth of the Specificationforming part of Letters Patent No. [05,841, dated July 26, 1970,

ratchet-plate a, and can he raised or lowered at will, so that thesubsoil-plow G, secured at the lower end ofthe beam E,may work at anydepthL desired. 4

At a suitable point on the plow-stock A is attached a clevis, H,whichpasses through slots in the beam E, and is there pivoted by means of abolt, c, passing through the same.

The wooden beam E and subsoil-plow G are intended to be used where thereis no pipeclay; but where there is pipe-clay I substitute a subsoiler,I, made entirely of iron. These two can hc readily interchanged;

, This plow cannot only be used a'subfsoler,

but also to prepare theland and work the crop.`

A cotton or corn planter may be readily attached, as also afertilizer-distributer.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The arrangement of the beam' C, stock A, ratchet-plate a, bolt b, nut d,subsoil-beam E, and clevis H, all constructed and operated substantiallyas set forth.

1n testimonythat [claim the foregoing I have hereunto set my hand this21st day of March,
